User information

How the dispenser works

Follett’s 25/50 series automatic-load ice and water dispensers are equipped with Follett’s 425 lb (181kg)/day

ice machine. In the continuous icemaking process, water freezes to the inside wall of the evaporator. A rotating

stainless steel auger carries the ice to the top of the evaporator where it is compressed and extruded through

an outlet port. The ice is then pushed through a tube to the storage hopper. When the hopper is full, a bin

thermostat opens and shuts the ice machine off. When the dispense mechanism is activated, a dispense motor

is turned on, causing the wheel to turn. This moves ice to the dispense chute where it drops by gravity into the

container held below the chute.

How SensorSAFE infrared dispensing works

Follett’s SensorSAFE infrared dispensing maximizes sanitation and minimizes the possibility of cross-

contamination by eliminating physical contact between the cup or container and dispenser. Sensors in the

panel use reected infrared light to detect the presence of the container and send a signal to a control board

which then activates the appropriate components for ice or water dispensing.

The SensorSAFE infrared dispensing package includes a cleaning switch under the left side of the front cover

which temporarily shuts off dispensing to allow cleaning of the panel and lenses. If the switch is not turned

back on after cleaning, the dispenser automatically resets after two minutes for normal operation.

SensorSAFE infrared dispensing also includes a time limit safety feature which automatically stops ice

dispensing after one minute of continuous dispensing. Dispensing can be resumed by moving the container

away from the dispenser and returning it to the activation zone.

Cleaning/descaling and sanitizing

Follett ice machines and dispensers, and their associated cleaning and sanitizing procedures, are designed

for use with potable water sources. The presence, or suspected presence, of infectious agents may call

for additional measures, including the replacement of components and more comprehensive disinfection

measures. Follett recommends that these cleaning and sanitizing procedures be reviewed with the appropriate

infectious agent subject matter experts to assure complete remediation.

Periodic cleaning/descaling and sanitizing of Follett’s ice and water dispenser and ice machine system

is required to ensure peak performance and delivery of clean, sanitary ice. The recommended cleaning

procedures that follow should be performed at least as frequently as recommended and more often if

environmental conditions dictate.

Cleaning of the condenser can usually be performed by facility personnel. Cleaning/descaling and sanitizing of

the ice machine system should be performed by your facility’s trained maintenance staff or a Follett authorized

service agent. Regardless of who performs the cleaning, it is the operator’s responsibility to see that this

cleaning is performed according to the schedule below. Service problems resulting from lack of preventive

maintenance will not be covered under the Follett warranty.

Service

Wiring diagram - Lever only

Lever models

The dispense wheel motor is energized through the power and ice dispense switches. The water solenoid

valve is energized through the power and water dispense switches. The ice machine is controlled through a

non-powered contact closure bin thermostat circuit. When ice builds up around the bin thermostat, the contacts

open, cutting the bin signal to the ice machine.

SensorSafe models

SensorSAFE models provide “touchless” ice and water dispensing. When a container is placed within the

actuation zone below the ice or water chute on SensorSAFE dispenser models, an infrared signal reects off

the container and is detected by the sensor. The sensor then sends a signal to the control board to activate the

appropriate components to dispense ice or water. LEDs on the board indicate when the board is receiving a

signal from the sensors.

A safety, shut-off feature automatically shuts off dispensing after one minute of continuous activation.

Dispensing can be restarted by moving the container away and then returning it to the actuation zone.

Dispensing can be temporarily suspended for cleaning by depressing and releasing the clean switch, located

under the left side of the top front cover. Depressing and releasing the button a second time will return the

dispenser to normal operating state. If the clean switch is not depressed a second time, the dispenser will

automatically resume normal dispense operation (CLN LED goes out) after two minutes. An LED on the control

board will light to indicate that the dispensing has been suspended by activation of the clean switch.
